Description

Technical Field

[0001] This utility model relates to a fixed support device for a drill frame of a roller cone drill in an open-pit mine, belonging to the technical field of drill frame equipment for roller cone drills in open-pit mines. Background Technology

[0002] Roller cone drills are the primary rock-breaking tools in open-pit mining blasting, and their performance directly affects drilling quality, drilling speed, and drilling costs. The working parts of a roller cone drill mainly consist of a power head, roller cone drill rod, rod stabilizer, and roller cone drill bit. Due to the limitations of the open-pit blasting environment, the service life of roller cone drills is reduced, and maintenance costs are gradually increasing. Therefore, improving the performance of roller cone drills and reducing maintenance costs is an important way to alleviate production pressure for enterprises at this stage.

[0003] The drill frame of a rotary drilling rig exceeds 26 meters in height. To enhance the strength of the drill frame, prevent deformation due to rotational torque, and maintain stability during operation or relocation, a traction support device is indispensable. In open-pit mining, the drill frame structure is easily damaged in open-pit operations and relocation. Components such as the tie rods, machine room beams, and frame stiffeners often deform, crack, or break due to their load-bearing capacity. This instability in the drill frame structure can easily lead to mechanical failures and reduced production efficiency. Furthermore, deformation of the machine room can affect the overall seal, potentially causing electrical faults in the open-pit environment. To prevent these issues, mining companies need to invest significant manpower and resources in maintenance, placing a heavy burden on maintenance personnel and delaying production, thus impacting efficiency.

[0004] Therefore, it is essential to strengthen and improve the existing drill frame support structure of roller cone drilling rigs to avoid safety accidents and ensure smooth production. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a stable support device for a roller cone drill frame. This support device can enhance the stability of the high drill frame during drilling operations, avoid mechanical accidents caused by damage to the high drill frame, reduce maintenance workload and maintenance time, ensure production progress, and improve production efficiency.

[0006] The technical solution to the above technical problem is:

[0007] A stable support device for a roller cone drill rig includes a high drill rig, a high drill rig support base, a back tie rod, a drill rig fixing traction device, and a cable reel. The lower end of the high drill rig is fixedly connected to the bottom platform of the roller cone drill. The high drill rig support base is installed on the upper end of the high drill rig. The upper end of the back tie rod is connected to the upper part of the high drill rig, and the lower end of the back tie rod is inclinedly fixed to the bottom platform of the roller cone drill. The drill rig fixing traction device and the cable reel are fixedly connected to one end of the bottom platform of the roller cone drill. The improvement is that it also has a fixed support rod. The lower end of the fixed support rod is fixedly connected to the connection between the lower end of the high drill rig and the bottom platform of the roller cone drill. The upper end of the fixed support rod has a collar, which is fitted onto the body of the back tie rod. The body of the fixed support rod is perpendicularly connected to the body of the back tie rod.

[0008] The aforementioned stable roller cone drill holder fixing support device includes a connecting column and a fixing plate at the lower end of the fixing support rod. The connecting column is cylindrical, and its upper end has two parallel clamping plates perpendicularly connected to the upper end face of the connecting column. The two clamping plates clamp the two sides of the fixing support rod. The lower end of the fixing support rod has a pin hole, and the upper part of the plate surface of the two clamping plates has insertion holes that correspond to the pin hole at the lower end of the fixing support rod. The pin connects the clamping plates to the lower end of the fixing support rod through the insertion holes and the pin hole. The lower end of the connecting column has two fixing plates, which are square plates connected at right angles to each other. The lower end of the connecting column has a sharp right angle shape. The inner sides of the right angle surfaces of the two fixing plates are welded to the two right angle sides of the lower end of the connecting column, and the outer sides of the right angle surfaces of the two fixing plates are welded to the connection between the lower end of the high drill holder and the bottom platform of the roller cone drill.

[0009] The aforementioned stable roller cone drill holder fixing support device comprises a collar at the upper end of the fixing support rod consisting of two half-rings and a connecting clamp plate. Each of the two half-rings has a horizontal connecting piece at both ends, with connecting holes on the connecting pieces. The two half-rings are fitted onto the back tie rod body, with pins used for fixing the connecting holes on the outer connecting pieces of the two half-rings. The connecting holes on the inner connecting pieces of the two half-rings are connected to the connecting clamp plate. The connecting clamp plate is an H-shaped plate, with pin holes on the upper and lower parts of the two straight plates of the H-shaped plate. The lower parts of the two straight plates of the H-shaped plate are respectively clamped... The two sides of the upper end of the fixed support rod are held together. The upper end of the fixed support rod has pin holes that are opposite to the lower pin holes of the two straight plates of the H-shaped plate. The pin shaft connects the lower part of the two straight plates of the H-shaped plate to the upper end of the fixed support rod through the pin holes. The upper part of the two straight plates of the H-shaped plate of the connecting plate is respectively clamped on the outside of the two connecting pieces at one end of the two semi-rings. The upper part of the two straight plates of the H-shaped plate is opposite to the pin holes of the connecting pieces of the two semi-rings through the pin holes. The pin shaft connects the upper part of the two straight plates of the H-shaped plate to the inner connecting pieces of the two semi-rings through the pin holes.

[0010] The beneficial effects of this utility model are:

[0011] The fixed support rod and the back tie rod of this utility model form a right-angle structure, which improves the support for the back tie rod structure and alleviates the pressure and mechanical damage to the fixed traction device of the drill frame connected to the back tie rod; the front end of the fixed support rod forms a stable support with the back tie rod through a collar; the right-angle plate surface of the fixed plate at the bottom of the fixed support rod reduces mechanical damage to the high drill frame by expanding the contact surface.

[0012] This invention reduces the failure rate of the back tie rod and the high drill frame structure, and reduces the mechanical pressure on the drill frame fixing traction device and the probability of hidden failures caused by mechanical structure damage, thus providing an effective guarantee for the efficient operation and stable operation of roller cone drilling rigs in open-pit mines.
